The three parameters control the exposure quantity together, the aperture refers to the size of the opening area of the lens, the shutter refers to the length of the light entering time, and the ISO is the level for setting the light sensitivity. The difference in exposure parameters affects the amount of exposure. During shooting, different scenes need different exposure amounts, so that shooting can be performed by using different exposure parameters, for example, the exposure parameters when a landscape shot is shot downwind are different from the exposure parameters when a person is shot. In addition to the difference in the selected exposure parameters among different scenes, different exposure parameters may be selected according to personal preferences, for example, if some people like the brightness of the image to be brighter and some people like the brightness of the image to be darker, the exposure parameters may be selected according to personal intentions. Therefore, the scene exposure parameter and the user exposure parameter set according to the user exposure intention need to be preset, then the average value calculation or the weighted average value calculation is carried out on the scene exposure parameter and the user exposure parameter, and the calculation result is used as the reference exposure parameter.
